CONDENSER FOR COTTON-GINS.

SPECIFICATION forming part of Letters Patent No. 418,088, dated December24, 1889. Application filed February 25, 1889. Serial No. 301,009. (Nomodel.)

To all whom it may concern:

Be it known that I, ABNER D. THOMAS, of Little Rock, Arkansas, have madea new and useful Improvement in Condensers for Octton-Gins, of which thefollowing is a full,

clear, and exact description.

Prior to the date hereof a single condenser has received the product oftwo or more cotton-gin stands-that is, the delivery from the gin-standswas into a common flue, which in turn led to a single condenser havingbut a single apartment, into which the entire product of the gin-standswas delivered.

In the present improved construction the condenser, while having but asingle shaft and whose drum is rotated as a single part, has its drumdivided into compartments, which respectively belong to the gin-stands,and are respectively connected therewith by independent fiues, theadvantages whereof being that the cotton is delivered more evenly to thecondenser. The operation of the remaining gin-stands is not interferedwith in the event of the flue leading from some one of the gin-standsbeing inoperative, and any excess of air-pressure from certain of theginstands does not work backward into the fine or fiues leading from theremaining ginstands of the series and clog the operation of thoseremaining gin-stands, and at the same time the benefit of a positivefree" delivery of the output of the gins derived from the operation ofone large condenser in combination with several gin stands is fullyobtained;

The most desirable mode of carrying out the improvement is exhibited inthe annexed drawings, making part of this specification, in which--Figure 1 is a plan showing two gin-stands, the condenser, and theindependent fines which'respectively lead from the gin-stands to thecondenser; Fig. 2, a broken side elevation of the same; and Fig. 3, avertical longitudinal section, upon an enlarged scale, taken on the line3 3 of Fig. 1.

Only those parts of the mechanism essential to an understanding of theimprovement are shown, and the same letters of reference denote the sameparts.

A A represent the two gin stands.

B B respectively represent the lines lead ing from the gin-stands to thecondenser O. The gin-stands are made and operated in the usual manner.The condenser in length is approximately if not quite equal to thecombined lengths of the gin-stands, and by means of a cross-partitioncit is divided Within and without the drum into two compartments 0' 0Fig. 1, with which respectively the fiues B B connect. The flues are notconnected with each other, but they respectively connect the gin-standswith the condenser-compartments c 0 and the product delivered from theginstand A passes solely into the compartment 0' and the productdelivered from the ginstand A passes solely into the compartment 0 Thecondenser-shaft c is driven in the usual manner, and in its rotation itcarries around the entire condenser-drum, and, saving as the condenseris modified or supplemented by the improvement under consideration, itsconstruction and operation are of the usual character, and the cotton isdischarged from each compartment 0 or 0 as indicated by the arrow :0,Fig. 3, and in a manner analogous to that in which cotton is dischargedfrom an ordinary condenser, and the dust passes into the dust-flue D.\Vhen more than two gin-stands are connected with the condenser, thatpart is divided into as many compartments as there are gin-stands and asthere are flues.

By the term condenser herein used is meant the combination of thecondenser-drum and the inclosing-casing, and the condensercompartmentsinclude the interior of the drum as well as the annular space betweenthe drum and the casing.

I claim The combination of two or more gin-stands, a condenser dividedinto compartments, and independent fiues connecting said gin-stands withsaid compartments, respectively, substantially as described.

Witness myhand this 31st day of January, 1889.

ABNER D. THOMAS.
